Hugh of Cluny and Adoption
Hugh, from a noble Burgundian family, was raised by his great-uncle, Hugh, bishop of Auxerre. He entered the monastery of Cluny aged 14, took his vows a year later, was prior by the age of 21 and abbot in 1049.
He was an advisor to nine popes and had a great influence on the church and the political world of his time. Under his abbacy Cluny built a new basilica, the largest church in the world at the time, consecrated in 1095, and he was a leading organizer of the First Crusade.
He is the patron saint of fevers.
